It was the Hillary campaign’s decision to help elevate Trump to the nomination and give him as much media exposure as possible, thinking that it would make it easy for her to win.
It was also them that ran one of the worst presidential campaigns in history, including telling people not to vote for her and neglecting to campaign in key swing states out of pure arrogant hubris.
Inescapable conclusion to anyone who isn’t a Hillary stan or otherwise a blind Dem party loyalist:
Hillary and her campaign are more culpable for Trump infesting the white house than anyone else outside of the far right echo chamber and foreign agents.
